Patented Apr. 8, 1930 PATENT OFFICE WILLIAM D. BURNS, OF AMENIA, NEW YQBK noLLEn 1 BEARING Application flied June 30,

My invention relates to roller bearings but more particularly refers to roller bearings as utilized in vehicles.

One object of my invention is to provide a 5 bearing wherein the load carrying unit is offset from the vertical centerline of the bear- Another object of my invention is to provide a three point bearing wherein the moving elements revolve with the minimum of friction.

A still further object of my invention is to provide a bearing having three revoluble units therein, one of which carries the load and the other two act as positioning or guide units.

I am aware that roller bearings of various types and classes have been employed but none contempiate the unique combination of novel elements utilized in producing the remarkable results produced by this particular device.

With these and other objects in View, my invention consists of the novel construction, arrangement of parts and combination of elements, hereinafter referred to, described, claimed and substantially as illustrated in the accompanying drawings, wherein similar numerals refer to like parts throughout the several views, in which Figure 1, is an end elevation of the bear ng.

Figure 2, is a side elevation of the bear ng.

Figure 3, is a cross section taken on lines 3-3 of Figure 2. v

Figure 4, is a longitudinal section of the load carrying unit.

Figure 5, is an end elevation of the load carrying unit.

Figure 6, is a plan of one of the roller re tainers.

Figure 7, is an isometric view of one of the adjusting eccentrics,

The bearing comprises two end frames 1 and 2, spaced apart by the shouidered bolts 3, 4 and v5, cash provided with nuts 6, between which are held two fixed rollers and one adjustable roller.

Each of these end frames has three lugs 7, 8 and 9, with bolt holes 10, 11 and 12, provided 1927. Serial No. 202,649.

for bolting the bearing to a supporting means, not show Each end frame also has a clearance hole 13, through which the shaft 31, may pass, which shaft engages three roller bearing units 1.4, 15 and 16.

Referring to Figure 4, the body 17, of 15 v and 16 is rigidly held between the end frames 1 and 2 and the part 14 is adjustably held thgirebetween, by the shouldered bolts 3, 4 an 5.

The roller bearing units 15 and 16, are the positioning or guide elements of the bearing and are 0 similar construction as the load carrying unit 14, which is adjustable as a unit between the end frames 1 and 2, by the cams 47 and is clamped in position by the screws 18 and 19, which pinch the cam after the load carrying unit 14, is located in position, as clearly shown in Figure 1, by bringing together the split portions 20 and 21 of the end frames 1 and 2.

Referring to Figures 4 and 5, the body 17, is comprised of a hardened rolling surface 20, a shouldered guide portion 21 and 22, and two outwardly promoting portions 23 and 24, which in the guiding units 15 and 16, enter into and engage'with the end frames 1 and 2, and in the load carrying unit enter into engagement with the cam elements 47.

Engaging the rolling surface 20, are six hardened rollers 25, rolling between and guided by the shouldered portions 21 and 22, all of which are held in spaced relation between the two retaining parts 26 and 27, by the shouldered spacing studs 28 and washers 29 and 30.

Each of the rollers 25, projects beyond the retaining parts 26 and 27 and engages a hardhe ld positioned by the 90 ened casing 28, and is inwardly projecting portions 36 and 37 which are integral with the said casing. o

The hardened casings 28, engage the shaft 31, and the part 14, adjusted to suit conditions by turnin the eccentric 47, by means of the nut shapeg extension 32.

The vertical centerline of the load carrying unit 14, is somewhat ofiset from the vertical. centeriine or. the shaft 31, with the object in view of utilizing the power of gravitation as a driving force, clearly shown in Figures 1 and 3.

The arrows in Figure 3, show the direction of rotation of the hardened rollers and the 5 shaft, wherein the shaft will roll upon the three casings and the casings will roll, each one, upon the hardened rollers therein and the rollers will roll upon the body which is fixed.

Having thus described the referred embodiment of my invention, I 0 not wish to limit myself to the exact construction shown, since it is evident that modifications ma be made without departing from the spirit 0 the invention or scope of the claims. I claim 1. In a roller bearing, the combination of two end frames, slidable over a shaft, each provided with a holding means, said frames split at the upper portion and having means holding two fixed guide rollers comprised of a tubular sleeve with a plurality of rollers therein between the said. sleeve and a fixed shaft and one eccentrically adjustable load carrying roller ofiset from the vertical centerline of said bearing, said adjustable roller for operating with said split portion provided with a locking means all of which rollers being in contact with said shaft and in spaced relation to each other and the said shaft.

2. The combination with a three point roller bearin of two end frames carryingtwo fixed gui ing units and one split to eccentrically, adjustahly and lockably carry a load carrying unit, each unit comprising a multiple of hardened rollers rotatable within a tubular retaining means, means guidin the said rollers upon a fixed body, a har ened sleeve provided with roller guiding means and the said end frames split and provided 40 with means for holding and positioning said eccentrically adjustable load carrying unit.

Signed at Amenia, in the county of Dutchess and State of New York, this as day of June, 1927. WILLIAM D. BURNS.
